Austria Email PSF/PSM/PSR/PSRR Heating & Cooling Buffer Tanks

The PS series represents high-performance heating and cooling buffer tanks ranging from 200 to 5000 litres, featuring energy-saving ECO SKIN 2.0 fleece insulation and versatile heat exchanger coil or flange configurations.

The Austria Email PSF / PSM / PSR / PSRR series of buffer storage cylinders provides premier hydraulic decoupling and thermal energy storage for central heating systems utilizing solid fuel boilers, heat pumps, solar thermal systems, gas boilers, or district heating.

Multiple buffer cylinders can be linked in battery/cascade arrays to tailor total thermal storage volume precisely to project demands. Additionally, when fitted with diffusion-tight Armaflex insulation, they can be utilized as chilled water buffer tanks in cooling systems and industrial heat recovery processes.

Model Designations

• PSM Series: Standard buffer tank without internal heat exchanger (200 to 5000 litres).
• PSF Series: Equipped with a 240 mm mounting flange for installation of finned-tube heat exchangers (RWT2) or screw-in/flanged electric immersion heaters (RSW) (500 to 5000 litres).
• PSR Series: Fitted with 1 large-surface smooth-tube coiled heat exchanger for solar or heat pump integration (500 to 5000 litres).
• PSRR Series: Fitted with 2 coiled heat exchangers to integrate solar collectors alongside a secondary heat source (800 to 2000 litres).

Key Features & Advantages

• ECO SKIN 2.0 Fleece Insulation: 100 mm polyester fleece insulation up to 5000 litres; hugs the tank tightly, eliminates thermal bridging, and features insulated connection caps with a rugged polystyrene outer jacket.
• Broad Capacity Range: Available in 12 volume increments from 200 to 5000 litres (200, 300, 500, 800, 825, 1000, 1250, 1500, 2000, 3000, 4000, 5000 L).
• High-Grade Construction: Manufactured from robust S235JR quality steel with powder-coated exterior finish (protective primer coating above 3000 L).
• Internal Stratification Plate: Built-in internal baffle plate (up to 2000 L) preserves thermal stratification and stabilizes flow turbulence.
• Comprehensive Socket Array: 9 threaded 6/4" (1½") connection sleeves (2" on 3000–5000 L) and 4 sensor/thermometer immersion sleeves (1/2").
• Operating Parameters: Maximum operating temperature 95°C (110°C for coils); 4 bar working pressure up to 2000 L, 3 bar for 3000–5000 L (10 bar for coils).
